Abstract (en)
[origin: WO2007125256A1] The invention relates to a multi-layer semi-rigid sheet material [10], that is resistant to temperatures above 124°C and has high gas impermeability and intended for the manufacture by folding of containers [20] defining an inner space for the packaging of heat treated products, a container of this kind [20], a method for obtaining such a multi-layer material [10] and a product packaging method. The multi-layer material [10] includes at least one so-called outer layer [11] of polymer material and one so-called inner layer [12] of polymer material between which the multi-layer material [10] has low gas permeability such that there is a positive gradient [14, 13] of sensitivity to damp of this gas permeability from the inside to the outside, said gradient allowing the multi-layer material [10] to dry by outward evaporation during a multi-layer material [10] stabilization phase consequent on the heat treatment of the packaged products.
